The device under test is constructed by a plurality of devices under test through a network.
Based on the development system, the development method of the present invention can be implemented by using the steps shown in fig. 2, and specifically includes:
1. the user inputs user input information into the case design unit: the user inputs test service data to the case design unit through human natural language or man-machine interaction; specifying variable parameters and data generation rules in the input test service data; presetting an expected result and comparing and judging rules;

8. and the use case design unit carries out display or breakpoint debugging according to the judgment result.
In order to make the method of the present invention more comprehensible, the following practical test cases are described as examples:
description of use cases: and configuring the device name as a random character string on the tested device, and testing whether the test is successful or not.
The testing steps are as follows:
running the following command lines on the device under test performs device name configuration:
#config terminal
# devicname [ random string ]
#end
The expected results are:
running a name detection command line on the device under test:
#show devicename
the device under test should come back:
# The devicename is [ random string ]
If the device playback is completely equal to the character strings, the test result is correct, otherwise, the test result is wrong.
If the above use case is to be realized, the implementation process of the invention is as follows:
s10, adding a verification point, namely verification point 1, by a user through a graphical User Interface (UI), and inputting a configuration command:
#config terminal
# devicname [ character string to be replaced ]
#end
S20, adding a variable parameter tmpAdomStr by a user, selecting a data generation rule as a random character string type, and replacing the front character string to be replaced by a grammar format of% tmpAdomStr%;
and S30, since the command sent by the verification point mainly serves as configuration issuing, no matching relation is filled in.
The above process is then repeated, adding a separate verification point for the test command line:
s10, adding a verification point, namely verification point 2, by the user through a graphical User Interface (UI), and entering an inspection command:
#show devicename；
s20, the verification point 2 does not need to generate parameters, only needs to use the existing parameters of the verification point 1, and does not fill in the parameter generation relation;
s30, adding a comparison judgment rule by The user through a graphical User Interface (UI), selecting The relation as equal to, and setting The expression value as The devicname is% tmpAdomStr%. It should be added that, in this example, only the "equal" relationship is used, and actually, there are many preset comparison and determination rules available for the user in the system, and flexible combination is possible.
When the design process of the use case is finished, the system converts the input information into the presentation layer data, stores and uploads the presentation layer data to the use case operation control unit, and converts the presentation layer data into the use case data of the presentation layer; the conversion into structured presentation layer data is for storage and transmission, reverse imaging and later modification.
S40, the analysis unit obtains the presentation layer data and analyzes and converts the presentation layer data into script language fragments;
s50, the parsing unit fills variable parameters into the script language fragments according to the data generation rule;
the parsed code may already be understood and executed by the execution unit.
S60, the execution unit executes the script language fragment and returns the device execution result data;
s70, the comparison and judgment subunit obtains the execution result of the execution unit, and carries out matching judgment according to the expected result of the presentation layer and the comparison and judgment rule thereof, if the judgment is correct, the step is shifted to S90 to output the test result;
and S80, interrupting. If the execution results of the verification points 2 are not correctly matched, if the user allows error interruption, the test environment is kept on site at the moment, a breakpoint debugging mode is started, the tested device establishes a new Shell command line connection window through another thread, and the user can directly connect to the device side to carry out real-time debugging in a similar SSH or Telent mode at the moment. After the real-time debugging is finished, the system re-executes the content of the current error verification point and continues to execute the subsequent verification points which are not executed; it should be noted that, in addition to debugging the false interrupt, the user may also use the interrupt command to force the interrupt and real-time debugging process at a certain location in the verification point, so as to assist the use case development process.
And S90, recording and outputting the test result.
The technical solutions claimed in the present invention include, but are not limited to, the above embodiments, and equivalents of the solutions of the present invention described in the above embodiments may be substituted by those skilled in the art without departing from the spirit of the present invention.
